Rachel Weisz has revealed she was nearly killed by a horse that had worked on Game of Thrones.

Appearing on tonight's (June 9) The Graham Norton Show alongside Martin Freeman, Anthony Joshua and Greg Davies, the actress told the story of how she was almost crushed by a horse that had previously worked on the HBO series.

After explaining that the horse had been taught to feign death whenever its left reign was pulled during filming for GoT (of course), Weisz added that the manoeuvre didn't work so well for her on the set of her new movie My Cousin Rachel.

"Galloping side saddle in a corset and a big frock isn't un-challenging," she said. "It was a bit of a balancing act.

"[The horse] had been taught to 'die' when the left rein was pulled so when I finished a scene and pulled on the left rein he did an elegant collapse on top of me.

"It wasn't un-painful," she added. "It was okay but there was a horrible silence on set until everyone realised I was alright."

My Cousin Rachel is based on a novel by Rebecca writer Daphne Du Maurier, which tells the tale of a young Englishman who plots revenge against his mysterious, beautiful cousin, believing that she murdered his guardian, but things get a little trickier when he begins to fall for Rachel's charms as well.

The film features Rachel in the eponymous role, alongside Hunger Games star Sam Claflin, Holliday Grainger and Iain Glen, and the trailer looks seriously creepy, with murder almost definitely in the air.

It's just lucky Rachel herself didn't end up murdered in the process.

My Cousin Rachel is released in UK cinemas on June 9, and you can catch Rachel on The Graham Norton Show tonight at 10.35pm on BBC One.
